What Is Dalacin C 150mg?

Dalacin C 150mg is an antibiotic capsule containing clindamycin hydrochloride as its active ingredient. It is classified as a lincosamide antibiotic and is available as a Schedule 4 (prescription-only) medicine in Australia.

Each capsule contains clindamycin hydrochloride equivalent to 150 mg of clindamycin. The medicine is intended for treating infections caused by susceptible bacteria, particularly when penicillin is unsuitable or cannot be used.

Doctors may prescribe Dalacin C 150mg for certain serious infections affecting the:

• Respiratory tract: Including specific lung infections such as anaerobic pneumonia, empyema, and lung abscess.
• Skin and soft tissues: For serious infections caused by susceptible bacteria.
• Bones and joints: Including certain bone infections and as an additional treatment in selected chronic bone and joint infections.
• Abdominal area: Such as peritonitis and intra-abdominal abscesses.
• Female pelvic and genital tract: Including certain pelvic infections, endometritis, and tubo-ovarian abscesses.

The choice of treatment depends on the type of infection, the bacteria responsible, and their sensitivity to clindamycin. Dalacin C 150 is not suitable for every infection.

What Is Dalacin C 150mg Used For?

Dalacin C 150 mg is prescribed for serious bacterial infections caused by susceptible anaerobic bacteria and certain strains of streptococci, pneumococci, and staphylococci.

Depending on the organism involved, its approved uses include:

• Serious respiratory infections: Such as anaerobic pneumonitis, empyema, and lung abscess.
• Skin and skin-structure infections: When the infection is caused by bacteria sensitive to clindamycin.
• Bloodstream infections: Including septicaemia caused by susceptible organisms.
• Intra-abdominal infections: Such as peritonitis and abscesses involving the abdominal cavity.
• Pelvic infections: Including endometritis, pelvic cellulitis, and certain post-surgical infections.
• Bone infections: Such as acute haematogenous osteomyelitis caused by susceptible staphylococci.

Clindamycin may also be used alongside appropriate surgical treatment for selected chronic bone and joint infections.

A doctor may consider this antibiotic when a patient has a penicillin allergy or when penicillin is not an appropriate option. Laboratory testing may be used to identify the bacteria and determine whether clindamycin is suitable. Dalacin C 150mg does not treat viral illnesses such as influenza or the common cold.

How Does Dalacin C Work?

Dalacin C works through its active ingredient, clindamycin, which interferes with the way susceptible bacteria produce proteins.

Clindamycin attaches to the 50S subunit of bacterial ribosomes, structures responsible for making proteins needed by bacteria to grow and multiply. By disrupting this process, it helps control bacterial growth and allows the body’s immune system to deal with the infection.

Its action depends on the type of bacteria and their susceptibility to the medicine. This is why a doctor may recommend bacterial testing before or during treatment.

How to Take Dalacin C 150mg?

Follow the instructions on your prescription and take Dalacin C 150mg exactly as directed by your doctor. The timing and number of capsules depend on the infection being treated.

For proper administration:

• Swallow the capsule whole with a full glass of water.
• Do not crush, chew, or open the capsule.
• It can be taken with or without food.
• Leave at least 30 minutes between taking the capsule and lying down.
• Space doses evenly throughout the day if you have been prescribed multiple daily doses.
• Continue treatment for the duration advised by your doctor.

Taking the capsule with enough water and remaining upright helps reduce irritation to the food pipe. If your symptoms do not improve within a few days or become worse, contact your doctor rather than changing the dose yourself.

Dalacin C 150mg Dosage

The prescribed amount of Dalacin C 150mg depends on the severity of the infection, the bacteria involved and individual patient factors.

According to the Australian Consumer Medicine Information, the usual adult dose is one 150 mg capsule four times daily. Higher doses may be required for more serious infections under medical supervision.

Do not increase, reduce or change the frequency of your capsules without consulting your prescriber.

Missed Dose

If you forget to take a capsule:

• Take it when you remember, unless it is almost time for your next scheduled dose.
• If the next dose is due soon, skip the missed one and continue with your regular schedule.
• Do not take two capsules together to compensate for a missed dose.

Ask your pharmacist if you are unsure how to manage a missed dose.

Overdose

Taking more Dalacin C 150 mg capsule than prescribed may increase the risk of unwanted reactions and require urgent assessment. If you suspect an overdose, even if you feel well:

• Contact the Poisons Information Centre on 13 11 26.
• Contact your doctor for advice.
• Visit the nearest hospital emergency department if necessary.

Dalacin C 150mg Side Effects

Like other antibiotics, Dalacin C 150mg may cause unwanted reactions in some people. Not everyone experiences them, and their severity can vary.

Dalacin C Drug Interactions

Certain medicines can affect how clindamycin works or increase the possibility of unwanted effects. Inform your doctor and pharmacist about all prescription medicines, over-the-counter products, vitamins, and herbal supplements you use.

Some medicines specifically listed in the Australian Consumer Medicine Information include:

Some medicines used during surgery may also interact with clindamycin by affecting muscle and nerve function. Do not start or stop any medicine without discussing it with your healthcare professional.

Precautions and Safety Advice

Before starting Dalacin C, tell your doctor about your medical history, allergies, and any medicines you currently take. Certain conditions require additional care during treatment.
